摘　　要：高温高压润湿性及界面张力仪可以真实模拟油藏条件测量接触角和界面张力。为了使高温高压润湿性及界面张力仪可以测量二氧化碳与原油最小混相压力功能,增加了高温高压气体进样系统,改进了原有油相、水相进样系统,使其功能得到扩展。仪器功能扩展后可以测量二氧化碳与原油最小混相压力,相对细管实验测量二氧化碳与原油最小混相压力的方法,该方法简单、快速,同时仪器的测量精度和使用范围也得到了提高,可以测量常温凝固的稠油等样品的界面张力、接触角及最小混相压力,且仪器的清洗和操作更加简单。The high-temperature and high-pressure wetlability and inlet＇facial tension instrument can simulate the reservoir conditions and measure the contact angle and interracial tension between oil and water. The oil and water sample injection systems of the instrument are improved and a gas sample injection system is added to the instrument in order to extent its function for the measurement of the minimum miseihle pressure of carbon dioxide with crude oil. Compared with the carbon dioxide-crude oil minimum miscible pressure measurement method using slim-tulle test, the tneast,＇ement method using the improved instrument ix convenient and fast, and of high measurement accuracy and wide measurement range. The improved instrument can be used to measure the interracial tension. the eontact angle and the minimum miscible pressure of the heavy oil sample solidifying at normal temperature, and its cleaning and operation is also very simple.
